Nhiễu Perlin 1D (Perlin Noise 1D)

The Perlin Noise 1D modifier adds one-dimensional Perlin noise to the stroke. The curvilinear abscissa (value between 0 and 1 determined by a point's position relative to the first and last point of a stroke) is used as the input to the noise function to generate noisy displacements.

This means that this modifier will give an identical result for two strokes with the same length and sampling interval.

Tần Số (Frequency)

How dense the noise is (kind of a scale factor along the stroke).

Biên Độ (Amplitude)

Lượng nhiễu biến dạng nét vẽ trong "Góc Độ".

Seed (Mầm)

The seed of the random generator (the same seed over a stroke will always give the same result).

Quãng Tám (Octaves)

The "mức độ chi tiết" of the noise.

Góc Độ (Angle)

In which direction the noise is applied (0.0 is fully horizontal).
